Maybe it's a technique of the director or screenwriter. In many movies, there are scenes of the hero peeing, some of which are straightforward and even have details of peeing. The association between peeing and not peeing is very different. Perhaps we can't understand the director's performance, perhaps to show that the hero is very serious in chasing demons and doesn't even have time to go to the toilet; Maybe it's to show his informal personality, and he can pee if he wants, who knows. . . . . After all, peeing is a very private thing, and watching others do private things will always leave a deep impression on those who see it. I don't know why there is such a big difference between urinating and not urinating. It may be the influence of toilet culture in China. If I were a director, I would arrange for Louis Koo to take a shit, just like when we go to the public toilet, we can always see some incredible advertisements.
